ENGELBERT GUEHNA, OF'SHEBOYGAN, WISCONSIN.

SCHOLARS COMPANION.

SPECIFICATION forming part of Letters Patent No. 567,342, datedSeptember 8, 1896,

Application filed June 17, 1896- To all whom it may concern.-

Be it known that I, ENGELBERT GUEHNA, acitizen of Austria-Hungary,residing at Sheboygan, in the countyof Sheboygan and State of Wisconsin,have invented certain new and useful Improvements in ScholarsCompanions; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, forming a part of thisspecification.

This invention relates to a scholars companion, which consists of platessecured to the face of one of the rails of an Ordinary school-slate forthe purpose of sharpening pencils, also a recess in one of said rails inwhich the pencil may be placed, said pencil adapted to be held thereinby a detachable cover formed by an ordinary measuring-rule, the objectsand advantages of which will be hereinafter pointed out and claimed.

In the drawings, Figure 1 is a perspective View of a school-slateprovided with a sharpening device in one of the end rails thereof and arule secured to'one of the side rails. Fig. 2 is a vertical longitudinalsection through a portion of the rail upon which the rule is secured,said view showing a groove in said rail and means for locking the rulethereover by means of the headed pins, which are locked in suitablekeyhole-openings. Fig. 3 is an enlarged perspective view of a portion ofthe slate shown in Fig. 1 with said rule removed. Fig. 4 is an enlargedperspective of the sharpening-plates removed from the slate andseparated to more clearly show their construction, and Fig. 5 is an endelevation of said plates when assembled.

Referring to the figures of reference, 1 designates a slate of theordinary pattern used for school purposes. 2 indicates one of the endrails, and 3 one of the side rails thereof.

4 represents a groove formed in the upper face of the rail 3, saidgroove being of sufficient size to permit of a pencil or crayon beingplaced therein. Formed in said rail, at the ends of said groove 4:, arecavities 5, and covering said cavities, flush with the face of the rail3, are suitable plates 5, said plates provided with suitablekeyholeopenings Serial No. 595,830. (No model.)

standing in the samedirection, as clearly shown in Fig. 3.

7 represents an ordinary measuring-rule,

and passed through the ends thereof are suitsaid pins are moved into theslot of said keyhole-openings, as clearly shown in Fig. 2.

9 refers to a plate, which may be of any suitable size, said plate beingprovided with an angled, serrated face, and projecting from said plateat the ends thereof and below the lower edge of said face areears 9,said ears having apertures formed therethrough.

10 indicates a plate of similar form as the plate E), but being of lessthickness than said plate and without the ears 9', said plate 10 adaptedto rest upon the ears 9 of the plate 9, and said plate 10 having anangled, serrated face, which,with the angled face of the plate 10, isadapted to form a V-shaped groove,

as clearly shown in Fig. 1; the plate 10 having apertures extendingtherethrough, which apertures are adapted to register with the openingsthrough the ears 9 of the plate 9, through which openings suitabledevices may be passed for securing said plates to theframe of the slate.It is desirable that a recess be formed in the rail 2 and said platesset therein, so that the upper faces of said plates may stand flush withthe face of said rail. The operation of sharpening a pencil by means ofthis plate is performed by drawing the pencil at the desired pitch alongthe serrated groove, the serrationsof said groove tending'to'rasp thepoint thereof.

It will thus be seen that the arrangement and formation of parts thusdescribed form a means for keeping a pencil in place when not in use, aswell as to provide .means for retaining a rule in position for readyuse, and by means of the plates 9 and 10 a pencil may easily besharpened in a short time the parts, as a whole, being compact, few, andsimple.

Having thus fully set forth my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. As an article of manufacture, a schoolslate provided with a groove inthe upper face of one of its rails, the cavities at the ends of saidgroove, the plates extending over said cavities, the rule having theheaded pins extending through its ends, said pins adapted to engage insaid plates and the serrated plates in the rail of said slate-frame, forthe purpose set forth.

2. In a scholars companion, a slate provided with a groove in the upperface of one of its rails, the cavities at the ends of said groove, theplates extending over said cavities provided with keyhole-openingsthere- ENGELBERT GUEHNA. Vitnesses EMIL SOHLEGEL, WM. BIERMAN.
